Today, as never before, the magnet which attracts the blessings from on high is teaching the Faith of God. The Hosts of Heaven are poised between heaven and earth, just waiting, and patiently, for the Baha'i to step forth, with pure devotion and consecration, to teach the Cause of God, so they may rush to his aid and assistance. It is the Guardian's prayer that the Friends may treble their efforts, as the time is short -- alas, the workers too few. Let those who wish to achieve immortality step forth and raise the Divine Call. They will be astonished at the spiritual victories they will gain. (letter 28 March 1953 on behalf S. Effendi)
(12:1)

When the friends do not endeavour to spread the message, they fail to remember God befittingly, and will not witness the tokens of assistance and confirmation from the Abha Kingdom nor comprehend the divine mysteries. However, when the tongue of the teacher is engaged in teaching, he will naturally himself be stimulated, will become a magnet attracting the divine aid and bounty of the Kingdom, and will be like unto the bird at the hour of dawn, which itself becometh exhilarated by its own singing, its warbling and its melody. (coc 297)
(12:2)

The teaching work should under all conditions be actively pursued by the believers because divine confirmations are dependent upon it. Should a Baha'i refrain from being fully, vigorously and wholeheartedly involved in the teaching work he will undoubtedly be deprived of the blessings of the Abha Kingdom. Even so, this activity should be tempered with wisdom - not that wisdom which requireth one to be silent and forgetful of such an obligation, but rather that which requireth one to display divine tolerance, love, kindness, patience, a goodly character, and holy deeds. In brief, encourage the friends individually to teach the Cause of God and draw their attention to this meaning of wisdom mentioned in the Writings, which is itself the essence of teaching the Faith -- but all this to be done with the greatest tolerance, so that heavenly assistance and divine confirmation may aid the friends. (coc 298)
(12:3)

"Teaching is the source of Divine Confirmation. It is not sufficient to pray diligently for guidance, but this prayer must be followed by meditation as to the best methods of action and then action itself. Even if the action should not immediately produce results, or perhaps not be entirely correct, that does not make so much difference, because prayers can only be answered through action and if someone's action is wrong, God can use that method of showing the pathway which is right." (rdc 39). 39)
